So sorry to hear about your issues.
I'm estranged from my controlling parents. A book I found that helped me is
If You Had Controlling Parents: How to Make Peace with Your Past and Take Your Place in the World by Dan Neuharth.
Neuharth explains 8 types of controlling parents (and parents can and usually do fall into more than one category). They are:
-Smothering (overbearing scrutiny)
-Depriving (conditional love)
-Perfectionistic (pressure to perform)
-Cultlike (rigid rules and beliefs)
-Chaotic (Unpredictable)
-Using (needing to be number 1)
-Abusing (bullying)
-Childlike (inducing guilt)
Anywho, this is the webpage of the book:
